Just completed installed Pedrollo (Italy band), surprisingly very quiet. Finger cross. Although hardly mentioned in the forum, but happy to know it fr the water pump seller who keep on insisting recommend me this brand. Earlier only tot of getting Grundfos for the reason reliability and quietness. Till give a try on this brand. Was happy and also within my budget.

Rm930 pump itself. Model have to look for the receipt.

where do you purchase it? compare to the grundfos model, which is quieter?

I have no idea which is quieter as I don't have any experience with Grundfos. Bought it in Melaka. Hope it helps...
